I don't think so. Baptism is not unimportant in terms of salvation.
1 Peter 3:21: "Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a good conscience, through the resurrection of Jesus Christ,"
That is perfectly OK to think what ever you want to. I am happy to try and explain this for you.
All I am saying is that Scripturally speaking, water baptism plays NO role in the salvation of the soul.
As with any single verse or passage, we discern what it teaches by first filtering it through what we know the Bible teaches on the subject at hand. In the case of baptism and salvation, the Bible is clear that salvation is by grace through faith in Jesus Christ, not by works of any kind, including baptism. So, any interpretation which comes to the conclusion that baptism, or any other act, is necessary for salvation, is a faulty interpretation.
Those who believe that baptism is required for salvation are quick to use 1 Peter 3:21 as a “proof text,” because it states “baptism now saves you.” Was Peter really saying that the act of being baptized is what saves us? If he were, he would be contradicting many other passages of Scripture that clearly show people being saved (as evidenced by their receiving the Holy Spirit) prior to being baptized or without being baptized at all.
A good example of someone who was saved before being baptized is Cornelius and his household in Acts 10. We know that they were saved before being baptized because they had received the Holy Spirit, which is the evidence of salvation seen in Rom. 8:9.
The evidence of their salvation was the reason Peter allowed them to be baptized.
Thankfully, though, we don’t have to guess at what Peter means in this verse because he clarifies that for us with the phrase
“not the removal of dirt from the flesh, but an appeal to God for a good conscience.” While Peter is connecting baptism with salvation, it is not the act of being baptized that he is referring to (not the removal of dirt from the flesh). Being immersed in water does nothing but wash away dirt. What Peter is referring to is what baptism represents, which is what saves us (an appeal to God for a good conscience through the resurrection of Jesus Christ).
